- From the System Selection Menu, select SRS, then Data List. In the Data List, select FRONT PASSENGER’S WEIGHT. The weight (T0) of the front passenger’s seat is displayed on the Data List. Write this measurement down as “T0” on a piece of paper.
- If the reading on the HDS (T0) is within ยฑ0.35 kg (ยฑ0.77 lbs), go to step 5.
- If the reading on the HDS (T0) is at or not within ยฑ0.35 kg (ยฑ0.77 lbs), do the following and repeat the procedure from step 1.
- Confirm that the seat has no interference with surrounding components.
- Remove the front passenger’s weight sensors (If they were not reinstalled), reinstall them, then repeat this procedure from the step 1.

- Divide (M) by 2. Write this calculation as “M1” on a piece of paper.
- Calculate the variance between (M1) and the HDS (T) with the following formula.
Variance = (T) – (M1)
T: Weight measured by the HDS with the weight on the seat.
M1: Half of the weight measured by the weight scale.
- If the variance is within ยฑ2.2 kg (ยฑ4.9 lbs), initialization is complete. Go to step 10.
- If the variance is at or not within ยฑ2.2 kg (ยฑ4.9 lbs), do the following and repeat the procedure from step 1.
- Confirm that the seat has no interference with surrounding components.
- Confirm that the weight was placed precisely in the center of the seat.
- Remove the front passenger’s weight sensors, reinstall them, then repeat this procedure from the step 1. If the variance is still at or not within ยฑ2.2 kg (ยฑ4.9 lbs), replace the front passenger’s weight sensors (if they were not replaced), then repeat this procedure from step 1.

i-HDS Diagnostic Software and J2534 Reprogramming Software
American Honda
Motor Co., Inc. ("Honda
") offers the i-HDS (Honda
Diagnostic System) software suite for the diagnosis and repair of electronic systems on Honda
and Acura
automobiles, and for the reprogramming of electronic control units (including, but not limited to, ECMs and PCMs). This software provides access to all Honda
and Acura
vehicle systems (access to the immobilizer security system requires aย Security Professionalย level software subscription and Vehicle Security Professional [VSP] registration with NASTF). To use the i-HDS software, you need to purchase one of our convenient subscription options. In addition, you will need a pass-thru Vehicle Communication Device (VCI) that is compliant with SAE J2534-1 and J2534-2 in order to communicate with the vehicle
Vehicle Communication Interfaces (VCI)
The i-HDS software supports the use of a generic pass-thru VCI that is compliant with SAE J2534-1 and J2534-2. However, Honda
recommends the Denso DST-i or the Bosch MVCI for use on Honda
and Acura
vehicles, as Honda
has worked closely with these manufacturers to ensure their hardware and our software interact safely and within the J2534-1 and -2 specifications, for both diagnostics and reprogramming. If you choose to use a generic VCI, please carefully consider the customer and technical support options you will receive from your chosen device supplier. Honda
does not provide technical or customer support for generic VCI devices.
The VCI Application Table below lists devices that either are approved and supported by Honda
or are known to have completed and passed an independent, exhaustive validation program with our i-HDS software suite.

Reprogramming with theย J2534 Rewriteย Application in i-HDS
Included in the i-HDS software suite is a new reprogramming application called J2534 Rewrite. This application is made available to all subscribers of the i-HDS software suite and replaces the previous generation software,ย J2534 Honda
Pass-thru Reprogramming Software.
This new application is compatible with generic VCIs that comply with SAE J2534. It must be used to reprogram any Honda
/Acura
vehicle equipped with ECUs that support reprogramming. Refer to the table below for legacy applicability for the programming of ECMs and PCMs. Though system dependent, late-model vehicles may be equipped with other ECUs that support reprogramming as well, e.g. ABS or VSA.ย J2534 Rewriteย must be used to reprogram these control modules, as instructed in an applicable service bulletin.
As shown in this table, not all legacy Honda
/Acura
models are equipped with a reprogrammable ECM/PCM. Furthermore, all 2007 and later models not listed in the table are fully supported with this application.
